Every audio file carries technical details you cannot see just by looking at the file name, things like its exact duration, bitrate, sample rate, and format. The Audio Metadata Viewer on File Tools Online reads that technical information straight out of your file and reports it back to you clearly, so you can check exactly what you are working with before you use, share, or upload it. There is nothing to install and nothing to configure, you upload a file and get a straightforward report of its real technical properties. It works the same way whether you are checking a single track or spot-checking a handful of files from different sources.

What Counts as Audio Metadata

The word metadata covers a couple of different things, and it helps to know which one you actually need. This tool focuses on technical metadata, the properties baked into the audio stream itself: duration, bitrate, sample rate, number of channels, and file format or codec. This is the kind of information that tells you what a file actually is, regardless of what it is named or labeled.

There is also tag metadata, things like song title, artist, album name, genre, or cover art, the kind of information you see in a music player's library view. This tool reads and reports technical file properties. It does not add, edit, or fix song title, artist, album, or other tag information. Both kinds of information are commonly called "metadata," which is exactly why the two get mixed up so often, but they live in different parts of a file and serve different purposes.

Common Uses for an Audio Metadata Viewer

Checking a file's real technical details is useful any time you cannot simply trust a file name, a label, or what someone told you about a recording. These are the situations people run into most.

  • Verifying Real Audio QualityCheck the actual bitrate of a file instead of trusting a label that says "high quality."
  • Confirming Project SpecsCheck sample rate and channel count against what a project, platform, or client requires.
  • Troubleshooting Playback IssuesCheck a file's format and codec when it will not play correctly somewhere.
  • Checking Duration QuicklySee a file's exact length without opening it in a media player.
  • Checking Before You UploadConfirm a file's format and technical details before sending it somewhere with strict requirements.
  • Auditing a Batch of FilesQuickly check the real properties of files from different sources before you use them together.

Does This Tool Edit Song Title, Artist, or Album Tags

No. This is a common point of confusion, since "metadata" gets used for both technical file properties and the song title, artist, album, and cover art tags you see in a music library. This tool reads and reports the technical side, duration, bitrate, sample rate, channels, and format. It does not add, edit, fix, or look up song title, artist, album name, genre, or cover art, and it does not connect to any online music database to find missing tags for you.

If what you actually need is to add or fix the title, artist, or album information stored in a file, that is a tag editing job, which is a different tool than this one. It is worth checking that distinction before you upload a file here, so you get the report you actually need on the first try.

A Free Alternative to Desktop Media Info Tools

Checking a file's real technical properties usually means installing a dedicated media info program or digging through a media player's file properties dialog. The Audio Metadata Viewer on File Tools Online skips both. There is nothing to install and nothing to dig through. You upload a file, and the report appears automatically. For a quick check on one or two files, that is faster than opening dedicated software.

Which Audio Formats You Can Check

The tool accepts common audio formats such as MP3 and WAV, so in most cases you can upload a file directly and get a report without converting it first. If your file is in a less common or older format, run it through the Audio Converter first, then check the result.

Understanding the Report: What Each Field Means

The report focuses on a handful of core fields. Here is what each one actually tells you.

  • Duration is the total length of the audio, usually shown in minutes and seconds.
  • Bitrate is roughly how much data is used per second of audio. Higher bitrates generally mean more detail retained, though the relationship depends on the format and encoding method used.
  • Sample rate is how many times per second the audio was measured when it was recorded or encoded, commonly 44,100 or 48,000 times per second for most music and video work.
  • Channels tells you whether a file is mono (one channel) or stereo (two channels), which affects how it sounds through speakers or headphones.
  • Format or codec is the underlying encoding used to store the audio, such as MP3 or WAV, which determines what software and devices can play it.

Tips for Using Audio Metadata

  • Do not judge a file's quality by its file size alone, two files of the same size can have very different bitrates depending on their length and format.
  • If a file sounds worse than expected, check its bitrate first. A low bitrate is one of the most common reasons audio sounds thin or compressed.
  • When you need a file at a specific sample rate or channel count for a project, checking the metadata first can save you a failed import later.
  • If you are troubleshooting a playback issue, checking the format and codec is often faster than guessing what might be wrong.
  • Keep a note of the technical details for files you use often in a project, so you can quickly confirm nothing changed if a file gets replaced or re-exported later.

Works on Windows, Mac, and Mobile

Because the Audio Metadata Viewer runs in your browser rather than as installed software, it works the same way on Windows, Mac, Chromebook, Android, and iPhone. There is nothing tied to one operating system, so you can check a file's technical details on whichever device you happen to have it on.

Audio Metadata Viewer Frequently Asked Questions

What is audio metadata?

Audio metadata is information about an audio file rather than the sound itself. This tool focuses on technical metadata, such as duration, bitrate, sample rate, channels, and format.

Does this tool edit song title, artist, or album info?

No. This tool reads and reports technical file properties. It does not add, edit, or fix song title, artist, album, genre, or cover art tags.

What information does the report include?

The report covers duration, bitrate, sample rate, number of channels, and file format or codec, the technical properties of the audio stream itself.

How do I check the bitrate of an MP3?

Upload the MP3 to the Audio Metadata Viewer. The bitrate is reported automatically along with the file's other technical details.

Does WAV support metadata?

WAV files can carry some metadata through optional chunks in the file format, but support is less consistent and less standardized than the tagging systems used by formats like MP3. Technical details such as duration, sample rate, and channels are always readable regardless of format.

Can I check the metadata of an MP3, WAV, or other audio file?

Yes. Upload your file to the Audio Metadata Viewer and it will report the technical details automatically.

Why does the metadata matter?

Technical metadata tells you what a file actually is, its real bitrate, sample rate, duration, and format, rather than what a label or file name claims. That matters when you are checking quality, troubleshooting playback, or confirming a file meets a specific requirement.

Is there a free audio metadata viewer online?

Yes. Upload your file and the tool reports its technical details automatically. There is no cost to use it.

What is the difference between technical metadata and tag metadata like artist and album?

Technical metadata describes the audio stream itself, duration, bitrate, sample rate, channels, and format. Tag metadata is descriptive information such as song title, artist, album, and genre, the kind you see in a music library. This tool covers technical metadata only.

Can this fix or repair a file's metadata?

No. This tool only reads and reports what is already in the file. It does not modify, fix, or repair the file or its metadata in any way.

What audio formats can I check?

The tool accepts common audio formats such as MP3 and WAV. If your file is in a less common format, convert it first with the Audio Converter, then check the result.

Can I use this on Mac, Windows, or my phone?

Yes. The tool runs in your browser, so it works the same way on Windows, Mac, Android, and iPhone without installing anything.
